Author here. The short version: softmax's partition function has complex zeros — from e^{iπ}+1=0 — that are invisible on the real line but cap safe step sizes at ρₐ = π/Δₐ. One JVP to compute. The repo has Colab notebooks if you want to poke at it. Happy to answer questions.
Nice work! The paper feels verbose at times and could use some editing to slim it down (also, equation 6 is just equation 5 in a box) but I enjoyed it a lot nonetheless.

That's such an american thing to say. A flu can be swine flu and fever can be Malaria or Dangue and one day delay can mean losing your life, so people in many parts of the world take fever and flu seriously.
PS: One of the highest points during my college prep days was when I managed to solve this kinematics problem from Krotov where the condition for a ball bouncing in a well to get out depends on the ratio of some parameters to be co prime. Good times.
There was a Mir Publishers bookshop close to my college in Patna and I would make regular visits in hope of landing gems like IE Irodov. Alas, most other Science books were so so and nowhere near their American counterparts (Halliday Resnick for Physics, Morrison Boyd for Chemistry comes to mind).
The Soviets did have the Landau book for physics, though I do not know if it was made available in India.
I should put a word for an Indian publishing house named Narosa which put out cheap editions of text books(mostly western) like the Feynman Lectures, Fermi's Thermodynamics, etc.
Landsberg's series on Elementary Physics[0] would be a more appropriate counterpart to Resnick & Halliday etc, targeted towards those preparing for university exams. Narosa has a great collection indeed.
Haha, this brings back memories! Spent so much time slouching over this book and taking a crack at the problems. Thanks for comment and triggering a trip down the memory lane :)
Yes, it is very normal in an unstructured life, many very smart graduate students at the top universities struggle with it. It is the curse of freedom. People don't realize a regular 9-5 job gives them routine, social commitments and a visible positive feedback on a good job done in a timely manner, and a negative feedback otherwise (both positive and negative social feedback are stronger than self-awarded rewards and punishments).
